The time period between when a person is actually infected with HIV and when antibodies to HIV can be detected in the test is called the window period.
Nearly everyone who is infected with HIV (99%) will have antibodies detected by 3 months after infection. However, currently used antibody tests are more sensitive than those used in the past.
Most people will develop detectable antibodies by 30 days after infection with HIV.
You are therefore able to do your HIV test at our clinic from the first month of exposure, then confirm your status once more in the third month.
